METHOD OF AND APPARATUS FOR CURLING FIBERS FOR UPHOLSTERY PURPOSES.

SPECIFICATION forming} part of Letters Patent No. 28 3,162,dated August14, 1883.

Application filed July 19, isse. Renewed July 12, less. No modeLi To allwhom it may concern/.1 I

Be it known that I, J OBIN GEORGE S'rErHENs,

I a subject of Great Britain, and residing at Brooklyn, Kings county,NewYork, have inbing, and pressure while winding onthe spindle, and for aperiod of time thereafter, in a mannercalculated to make muchstifferfibers and more rigid curls than as heretofore made by twistingor crimpingthe fibers.

The apparatus which I prefer to use consists of a steam or gas heatedrevolving spindle and a similarly-heated trough, between which and thespindle the fibers are delivered by feedrollers, so as to coil on thespindle along its whole length between it and the trough, by

- and then discharged, all as hereinafter fully described, referencebeing had to panying drawings, in which Figure 1 is partly a plan viewand partly a horizontal section of the said apparatus. Fig. 2 is asideelevation. Fig.3is a sectional elevation taken on line 09 00, Figs. land2; and

the accom- Fig. 4. is a perspective view of a bunchof coiled, heated,rubbed, and pressed fiber as it is delivered from the machine.

it represents atapered spindle arranged hOI'i-r zontally in bearings band a suitably for being rotated at a high' speed by a belt 011 apulley, d, one of its bearings, b, being chambered, as

at e, for a circulation of steam for heating the p and the spindle.

stripping the coils off from the spindle when .1 completed.

To begin with, the rollers being shifted to the outer end of thespindle, the carriage is, striking the head I of rod m, will throw camor down against arm 0 of the trough g and shift the trough into closeproximity to the spindle a, ready for pressing the fibers to be suppliedby rollers h against the spindle. At the same time said carriage will,by pulling rod 12, by

contact with head (1/ thereof and shifting.

clutch-lever b, engage clutch q with pulley a", sojthat it, being turnedby a belt from pulley s on the main shaft, will revolve shaft 15 bywheels u, whicl 1,sets the feed-rollers in motion atthe same time thatthe crank-wheel 1;

begins to draw said rolls along toward the base of the spindle by therods w 00 and bellcrank y. The feed-rolls, being then turned by thefeather a,,along which the lower roll slides on the shaft t, will supplythe fiber to the spindle, to be drawn aroundand coiled on it, between itand the trough. 5 until the rolls have reached the 'base of the spindle,when case k, striking a collar, 2, onrod 1), will shift clutch q out ofgear, stopping the rotation of the rolls. At the same time. said casewill strike the collar b of rod on and throw up cam 12, so as to lettrough g slack away from spindle a sufficiently to allow scraper j todischarge the coil *0 from the spindle by the return motion of case isto the place of beginning again, as

before.

Ido notlimit myself to the horizontal arrangement of the spindle a andheating and rubbing trough, forjthey may be arranged vertically, withthe points downward, the rollers hbeing also arranged vertically andmade to shift up and down; neither do I limit myself 0 -ters Patent,is-'- l. The method of coiling and setting fibers for upholsterypurposes,by winding them on a spindle while subject to heat andpressure, substantially as described.

2. The method of preparing fibers for upholstery purposes, by coilingand, rubbing said fibers while subject to heat and pressure,substantially as described. r

3. The combination, in amachine for coiling and setting fibers forupholstery purposes, of a rotary spindle and a rubbing-trough,substantially as described.

4. The combination, in a machine for coiling and setting fibers forupholstery purposes, of

' rollers arranged to slide along the spindle for coiling the fibersthereon, substantially as described.

8. The combination, in a machine for coiling and setting fibers forupholstery purposes, of a rotary spindle, a rubbing-trough, andfeedrollers arranged to slide along the spindle for coiling the fibersthereoin'and stop mechanism for arresting the feed-rollers for thedischarge of the coils, substantiallyas described.

9. The combination, in a machine for coiling and setting fibers forupholstery purposes, of a rotary spindle, a rubbing-trough, feed-rollersarranged to slide along the spindle for coiling the fibers thereon, stopmechanism for arresting the feed-rollers for the discharge of the Icoils, and a discharger for discharging said coils, substantially asdescribed.

10. The combination, in a machine for coiling and setting fibers forupholstery purposes, of a rotary spindle, a rubbing-trough, feed-rollersarranged to slide along the spindle for coiling the fibers thereon, stopmechanism for arresting the feed-rollers for the discharge of the coils,a discharger for discharging the coils, and mechanism for returning thefeed-rolls along the spindle and starting them and renewing the feedingof the fiber when the coils are discharged, substantially as described.
